　　[iyunv@centos63 keepalived-1.1.20]# ./configure --prefix=/usr/local/keepalived
　　configure: error: Popt libraries is required

　　Keepalived configuration
------------------------
Keepalived version       : 1.1.20
Compiler                 : gcc

[iyunv@centos63 kernels]# pwd
/usr/src/kernels
发现这个目录为空需要安装kernel-devel,yum安装比较简单
　　[iyunv@centos63 kernels]# yum install kernel-devel
　　解决方法如下：
　　[iyunv@centos63 keepalived-1.1.20]# ./configure --with-kernel-dir=/usr/src/kernels/2.6.32-358.11.1.el6.i686/
